New synthesis route for Mo–V–Nb–Te mixed oxides catalyst for propane ammoxidation Original Research Article

Several methods for preparing Mo–V–Nb–Te mixed oxides were examined. Hydrothermal treatment gives a precursor of ammoxidation catalyst which shows twice as high activity after calcination as the catalyst prepared by the known dry-up method. Mixed oxides prepared by solid state reaction give rather poor activity. It has been suggested that the higher activity of hydrothermal treated catalyst is related primarily to its higher surface area.
